2018 – 2021

Objective:A critical mass of Indian building sector (developers/builders and design professionals) adopt EETC building design as standard practice.

India like almost all societies has a long tradition of designing and constructing buildings taking into account the local climate. However, during last 3 decades this tradition has weakened because of a variety of factors, including availability and wide application of new materials like glass and aluminium, imitation of designs from colder climates of Europe and USA, increased access to mechanical ventilation and cooling as well as electricity to operate these systems, etc. Several recent initiatives such as ECBC, BEEP, green building certifications, etc. are trying to reintroduce the concepts of climate responsive design, energy efficiency and thermal comfort. While awareness of energy efficient and thermally comfortable (EETC) building practices has increased due to these efforts, limited impact of this is observed in practice in India.

Planned Activities:

  • Competencies of selected builders and developers for EETC building design are strengthened: BEEP will work with selected builders and developers (in different urban clusters / states) to raise awareness about EETC buildings and build their capacities (technical capacities and processes) so that they are able to put into practice the knowledge on EETC buildings.
  • National award on EETC buildings:India is a large country and innovative EETC buildings are being designed and constructed. But the efforts of the building industry stakeholders involved in such projects are not adequately recognised and promoted by the government and the society. To address this gap, BEEP will institute a national award, conferred by the Govt. of India (Ministry of Power / BEE) on energy efficient and thermally comfortable (EETC) building design.
  • Case studies on EETC buildings:There is a lack of well-documented EETC building case studies, and performance data of such buildings is nearly absent. Absence of performance data and case studies makes it difficult to convince the building industry as well as the government to adopt EETC buildings. BEEP plans to develop case studies to address this issue.
  • Strengthening of Architecture and Engineering education system on EETC buildings:BEEP will undertake measures to address the gaps on EETC building design principles and design processes in architectural and energy engineering undergraduate and post graduate courses.
  • Developing a public-domain Computational Fluid Dynamics (CFD)1 based interface for natural ventilation design:Natural ventilation is a key strategy to improving thermal comfort and energy efficiency in buildings, especially in multi-storey residential buildings. BEEP will develop a methodology/tool, based on CFD software available in the public domain, for designing for natural ventilation, with focus on affordable housing projects.

1Computational fluid dynamics (CFD) is the use of applied mathematics, physics and computational software to visualize how a gas or liquid flows - as well as how the gas or liquid affects objects as it flows past. CFD analysis is a useful tool for designing ventilation in buildings.

What is a charrette

One of the key objectives of the Indo-Swiss Building Energy Efficiency Project is to help Indian builders and developers in adopting new processes, tools and technologies for designing energy-efficient buildings. BEEP believes that cost effective energy efficient design is possible by following an integrated design process and a “charrette” or an intensive design workshop is an effective tool to implement the integrated design process. Integrated Design means that the client, the architect and the engineering design team start working on the project together right from the beginning, based on the client brief. Doing this allows to tap the largest energy saving potential with minimum effort and cost.

BEEP Integrated Design Charrettes are conducted over 4 days by a team of senior Swiss and Indian architects and engineers, for selected building projects in their early design stage. The objective of these charrettes is to develop a viable energy concept for the building project.

Till date BEEP has conducted charrettes for 11 commercial projects. The potential for energy savings as a result of BEEP initiatives were in the range of 25% to 50%.

Technical Assistance

Selected projects would be assigned a BEEP expert team, consisting of three to four Swiss and Indian experts (architect, building energy expert, HVAC [heating, ventilation, and air-conditioning] expert, etc). The technical assistance from the team would be available in three steps as described below:

Step 1 Preliminary analysis: Based on the concept design description, data, and drawings provided by the building project, the BEEP expert team will prepare a basic energy simulation model of a part of the project to analyze energy-efficiency options and define the baseline energy performance.

Step 2 Integrated design charrette/design work shop: The BEEP expert team would organize a design charrette (design workshop) of two to three days’ duration at the premises of the builder/developer. The participants in the charrette would be the builder/developer management team, the project design team, and the BEEP expert team. The project design team should include at least the client, the architect, and the HVAC/Mechanical, Electrical & Plumbing MEP consultant. Through a structured collaborative process and effective use of energy simulation tools, the charrette would come out with recommendations for an energy-efficient design. The recommendations would cover master planning, building massing, envelope solutions, energy supply, daylight, bioclimatic features, and advanced HVAC system design.

Step 3 Post-charrette support: After the charrette, the BEEP expert team will continue to provide technical assistance to the design team until the schematic design is finalized (typically for a period of 6 months). The BEEP expert team will carry out additional simulation studies while integrating the revised project design features.

The post-charrette technical support by BEEP will also include two meetings:

  • One meeting will be held before finalization of the schematic design. The objective of this meeting is to provide specific design inputs to the selected building project by the expert team.
  • A second meeting, a wrap-up workshop, will be held after the finalization of the design. The objective of this workshop is to validate the final design, and to assess the savings achieved. In addition, an interactive evaluation session will be organized to assess the impact of the charrette, and draw lessons for future charrettes.

For these exchanges, modern communication tools such as video conferencing and other online collaborative tools will be used. The Swiss experts are not expected to attend post-charrette meetings or workshops physically.

BEEP will bear all the costs of the BEEP expert team, which includes their professional fee, travel, boarding, and lodging expenses.

The BEEP team would also carry out follow-up activities to monitor the application of the charrette recommendations in the project at regular intervals.

About the Design Competition

BEEP had organized a Design Competition for External Movable Shading to create innovative, India-specific designs and solutions. The project has provided technical assistance to the winning designs in the form prototype development and testing to make them finished articles which can be launched in the market.

The design competition was conducted for 2 categories named after the most common application in buildings:

  1. Residential Sector (simple shading system): The shading systems will block all solar radiation (heat as well as light). These are expected to be simple, low cost solutions which will find wider applications in residential buildings.
  2. Commercial Sector (shading and day-lighting system): The shading systems will block the heat component of solar radiation but will provide effective natural day-lighting. These should be sophisticated mechanisms (can include sensors and automation) which find more application in commercial office buildings.

The competition was structured in two stages for both sectors, namely, Design Stage (Stage 1) and Mock-up Stage (Stage 2).

At the design stage, the focus was primarily on creative and innovative designs and a list of design were finalized. During the mock-up stage, shortlisted designs were asked to develop working mock-up models to test their functionality and effectiveness.

Due importance was given to both aspects while deciding the final winners and winners were decided after completion of the mock-up stage.

Objectives of the Design Competition:

The objective of this competition is to help bring the India-centric external movable shading system designs to the domestic market so that architects, product designers, HVAC engineers and others to use these systems/concepts in the buildings that they are associated with.

About External Movable Shading Systems

What are External Movable Shading Systems
External Movable Shading Systems are installed on the windows and glass facade of buildings which dynamically control the solar heat ingress and the visual light transmission. Controlling the solar heat ingress has a significant impact on the cooling/HVAC load of the buildings. Sophesticated systems also provide natural day-light control. 

Why External Shading instead of Internal Shading
The Solar Heat Gain Coeffiecient (SHGC) of internal blinds is more than 40% while that of a external shading system is less than 12%. The diagrams below demonstrate the reason for this low SHGC and the significance of external shading systems. 

Internal Blinds External Blinds
As the shading system is behind the glass pane, the heat enters the building and the Solar Heat Gain Coefficient (SHGC) is more than 40% As the shading prevents a significant proportion of heat from entering the building, the SHGC can be reduced to less than 12%

Types of External Movable Shading Systems
Disclaimer: The motive of provide examples of movable shadings systems is to give the participant an idea about existing systems. This is not an exhaustive but instead an indicative list. The participant is recommended to use this only as a reference. The design competition promotes innovative, indigenous, India-specific designs. 

1) Simple Systems which provide only Shading

1.1) Wooden Shutters

1.2) Roller Blinds

1.3) Awnings

1.4) Fabric Blinds

2) Systems with Shading and Day-light control

2.1) Horizontal Lamela Blinds

2.2) Vertical Lamela Blinds
